Command Center

Changelog

See what's new in each release of Command Center

1.0.12026-06-13

Highlights

  • Ask a coding agent for a walkthrough of code within any diff range, not just your current changes. Use it to ask what changed, ask for an explanation of a bug fix, or even to keep up with PR comments. For best results, explicitly state "use the walkthrough tool"

    Before

    An agent chat prompt asking for a walkthrough showing how all PR comments have or haven't been addressed, including each PR comment verbatim

    After

    The generated walkthrough titled "PR #1288 — How review comments were addressed", stepping through each inline comment

    Ask in plain language (left), and get a generated walkthrough over exactly that diff range (right).

New Features

  • Command Center now warns you before generating a walkthrough that would duplicate one you've already created.
    A confirmation dialog warning that a walkthrough for this commit range is already being generated, with Cancel and Create anyway buttons
  • Recent Commits dropdown now shows commit dates.
    The diff comparison dropdown listing recent commits, each with its commit date shown alongside the message
  • Syntax highlighting for .mjs files in the diff viewer.

Improvements

  • An alert toast now shows your remaining credits the moment you start a walkthrough or refactoring.
    A toast reading "Spending a walkthrough credit" showing the number of daily and one-time walkthrough credits remaining
  • Claude 5 Fable now offered for walkthroughs and refactorings.
  • Renamed "Sync Main" to "Pull from main" and added tooltips to the dropdown actions.
  • The command dock now opens automatically when you create a workspace.
  • Performance improvements to diffs of large codebases
  • The empty-session view now offers an action to take instead of a passive "no session" message.
  • Improvements to the caret for collapsing and expanding diffs
  • Hotkey suggestion toasts now dismiss themselves after 10 seconds.
  • Better message when comparing across a diff range that has no net changes
  • Improvements to keeping the live diff viewer synched with the code, even during heavy file activity.
  • Archiving the active workspace no longer jumps you back to the root workspace a few seconds later.
  • No longer show two hotkey-hint toasts at the same time.
  • Minor improvements to text throughout the app

Bug Fixes

  • Running a long-running TUI in the terminal, closing the tab, and switching back no longer causes the TUI to be malformatted
  • Fixed errors rendering the how-to videos in the Electron app
  • Fixed a rare mismatch in file ordering between the diff viewer and the sidebar tree (occurs when e.g.: there is a folder called server/, and a file called server-simple)
  • When viewing the snapshot viewer on top of a walkthrough, the arrow keys now navigate through snapshots, not the walkthrough
  • If you select a workspace being set up, can still view the settings and how-to pages
  • Fixed the progress-bar hover incorrectly showing a usage-limit tooltip.

1.0.02026-06-08

Highlights

  • Next-gen walkthrough viewer: be given a tour through a diff, fully in context
  • Use Command Center in your existing tool: add our skill to your coding agent, then ask it for a walkthrough.
  • Custom walkthroughs. Want a walkthrough of anything other than "here's everything that happened in a diff?" Like, want Claude Code or Codex to figure out a bug, and then explain it with a walkthrough rather than a wall of text?" Just ask, and it can do so
  • New sleep mode controls: Keep agents running, even when your laptop is closed.
    Settings showing three-level sleep / keep-awake behavior

New Features

  • Attach images to per-line agent feedback
    Per-line agent feedback widget with an attached image
  • Write multiple feedback comments at once
    Two inline feedback composers open on different changed lines in the diff viewer
  • Installed skills now appear alongside slash commands in the "/" autocomplete in agent chat
    The "/" autocomplete listing commands and skills, with SKILL badges
  • Command Center now asks for confirmation before quitting while coding agents are still running
    Confirmation dialog warning that agents are still running before quit
  • Rebuilt diff-scope picker with plain-language presets
  • Command Center now teaches you keyboard shortcuts
  • Configurable refactoring explanations: choose how thorough the explanation is (thorough / standard / terse) and optionally include the real code diff of the change
  • Workspace creation is effectively instant (can start agent sessions while it's still initializing)
  • Archived workspaces automatically deflate to reclaim disk space, and re-inflate on demand when you reopen them
  • Windows installer is now code-signed, and macOS DMGs carry a stapled notarization ticket, for a smoother, warning-free first launch

Improvements

  • Much faster diff rendering
  • Major backend speed improvement
  • Improved robustness of the walkthrough generation process
  • Improved speed and reduced token usage of the organize-file refactoring thanks to better prompt caching
  • Cancelling walkthrough generation now also cancels in-flight model calls
  • Sending a prompt from the fullscreen editor now collapses back into the normal agent view
  • Updated how-to videos for adding projects, snapshots, and generating walkthroughs
  • Archiving a workspace is now effectively instant — cleanup happens in the background
  • Forking a workspace properly carries over unpushed commits from the source workspace and any dirty submodules
  • Better error message when a coding agent failed to launch (e.g.: when it's managed by asdf and not properly initialized)
  • On macOS, system permission prompts now explain that an AI coding agent needs the access, instead of a generic message
  • Latest frontier models: Claude Opus 4.8 and Sonnet 4.6 are now available in the model picker
  • Pull Request connection failures now show clearer GitHub CLI remediation steps
  • Clearer feedback when copying a file path: clicking the copy button now shows a green checkmark and a "Copied!" tooltip
  • Inline feedback is now attributed to the exact commit its line belongs to, so comments stay tied to the right version of the code
  • Refactoring now ignores version-control metadata files when scoping changes
  • Command Center now warns and asks for confirmation before generating a walkthrough on a very large diff
  • Clearer reason shown when the desktop app fails to start, instead of a generic failure
  • The inline per-line feedback popover now stays a fixed size and anchored in view, instead of resizing or drifting off-screen
  • When doing a refactoring with Claude Code as the default coding agent: Command Center will prevent Claude from making edits outside the workspace
  • Improved refactoring UX: can no longer accidentally send a prompt to an in-progress refactoring session, which cannot properly answer the prompt
  • The button to cancel an in-progress walkthrough is now a distinctive red stop button, so it is easy to spot

    Before

    Generating indicator with a muted grey cancel square

    After

    Generating indicator with a distinct red stop button
  • The app aggressively avoids holding the git lock, especially for jj repos

Bug Fixes

  • Fixes to detecting and running Codex and Claude CLIs in the Electron app. (npm version was fine)
  • Files that were both renamed and modified now render correctly in the diff viewer
  • Improvements to error messages if refactoring fails
  • Fix (Electron-only): Sign-in, GitHub, and autorun callbacks now use the correct backend port
  • If a workspace crashes mid-setup, it will later heal automatically

  • Command Dock automatically opens after creating a new project
  • Mixed diff mode is now enabled by default: in split view, add-only and delete-only files render in unified layout to avoid wasted empty panels

Improvements

  • Many other improvements to the "Install coding agents" flow
  • Better communication of coding agent failures, fixing some cases that failed silently
  • Walkthrough highlight labels are now anchored to absolute file line numbers, so they stay correct even as surrounding code shifts
